SASH-QPERATING' MECHANISM.

Application filed August 7,

This invention relates to'windows of the swinging sash type and it refers more particularly to certaln improvements in the op.- erating mechanism for the sashes, its principal obJect being to provide a mechanism of the character designated, which will be completely hidden from View, yet positive in its action.

A further object of the invention residesin the capability of the mechanism to provide vfor selective raising and lowering of the sashes, either individually, in pairs or collectively.

Still further, the invention proposes, by reason of the positive action of the sash operating mechamsm to maintain locked position of the sashes, irrespective of their positions whether at extremes or intermediate such extremes.

With these principal objects in view, other 1 objects and practical advantages of the invention, including its salient features of construction and arrangement of parts, will become apparent as the description proceeds, taken'in connection with the accompanying drawings wherein- Figure 1 represents a front elevational view of a window constructed according to the present invention.

views ofthe lever employed for latching'the windows against movement.

Flgure 19 is a detail view of a partof the operating mechanism by which the upper sasles are selectively controlled from below, an I I Figure 20 represents a fragmentary plan view of an upper corner of the window to show the relative positions of the operating arms.

In proceeding more in detail with the drawings, the side stiles 1 of the invention are each provided with stops 2, as particularly apparent in Figure 7, and as aprecautlon against possible entrance and accumulation of water in the compartments occu- V pied by'the operating mechanism, channels 3 aredefined by the stops? down which'the water may run, to be discharged at the downwardly pitched sill 4, as in Figure 6.

In order to form a conservative joint between the sashes 5, they will be seen in Figure 6 as being preferably stepped to snugly conform when in closed position, one with the other.

The sectional front elevation shown in Figure 4 discloses that a plurality of vertical screw threaded shafts 6 are arranged in compartments situated in opposing stiles 1, the ends of Which, as a precaution against wear, are rotatably mounted in bosses 7 in the crown bar 8 and sill 9. On the lower end of each shaft 6 is afiixed a beveled pinion 10, and a horizontal shaft 11, mounted in bearings 12 within the sill 9, carries anumber of similar pinions 13'so arranged as to engage the pinions carried by the vertical shafts 6. At the approximate center of the 7 horizontal shaft 11, a pinion 14 is mounted in a bearing 15 securely affixed to the inside of the sill 9-, and has protruding outwardly a squared shaft 16, upon which an operating crank 17 may be conveniently applied to rotate the horizontal shaft 11, and consequently the vertical shafts 6, simultaneously. Ob-

servance to Figure 6 will disclose that the pivotall stationary with respect to the window fac- Figures 14 to 16 inclusive all illustrate a particular form of controlling latch 24,

which forms an o erative part of the collar.

20 to which the rst mentioned arm 19 is attached. U on this latch depends tie movement 0. its respective sash, and it is through the same that selective raising and lowering is accomplished, as will become apparent presently. It will be noted in the mentioned figures that a segment of threads 25 are formed integral with the to of the member which conform with the he ix of the threads on the vertical shaft 6, and when urged forward on its pivot 26 to effect such enga ement, the collars 20 will move on the shafts accordingly with the direction of rotation thereof.

Referring now particularly to the means by which selective actuation of the sashes 5 is accomplished; It will be observed in Figures 1, 2, 3 and 6, that the front facing of the windows are apertured said a ertures being covered with an aperture plate 27, through which a plurality of switches rotrude, and are conveniently accessible fi om the inside of the window. These switches are mounted upon a bracket 27 and are characterized in individual pairs according to their connection with: the res ective sashes 5, by the references 28, 29, an 30. An opcrating rod 31 is connected, as in Figure 6, to each of the switches 28 and 29 and extends upward flush with the facing in a suitable covered channel provided therefor, to where it enga s a pivoted lug 32, two of which are mm for eachof the sashes, one for either si e. The lugs 32 are substantially S- shaped as shown in detail in Figure 19, so as to increase the leverage thereof when the switches are 0 erated. The inner free end of these lugs fi'ictionally engage the tail of the latch 24, and since these lugs are held normally in operative engagement with the vertically situated shafts 6 by a leaf spring 33, shown in Figures 12 and 13 ressure against the tail of the latch obvious y urges the latter inward against the resistance of these springs and releases the thread segment 25 of the lug from its engagement with the helix of the shaft 6.

It will be understood that each sash 5 is provided with a pair of switches, and as exemplified in Figure 1, these switches are situated upon either side of the sash. For example, switches 28 control the. u per sashes, switches 29 control the interme iate sashes, while the switches 30 control the bottom sashes. The intermediate switch 29 is not required to have an operating rod 31, slnce it is in alinement with its respective sash. It may be stated that these switches may be all dispensed with if desired, since their operativeness only extends to the selective actuation of the sashes, and only indirectly functions when the sashes 5 are raised simultaneously. In order to dispense with the switches, the interior periphery of the sleeve 20, shown in Figures 8 and 9 may be screw threaded and the latches 24 deleted from the structure.

The windows are of such compact construction as to enable them to be effectively installed in large dwellings, commercial buildings, hotels and the like and areespecially valuable for office buildings, since the draft through the windows may be regulated to a nicety, and due to their construction, ma effectually prevent blowing of papers, ant entrance of rain. The frames in which the sashes are mounted may be constructed of wood, metal or other material applicable to the purpose.

Referring now particularly to the o eration of the window and minor details of construction, the Figure 6 provides a comprehensible reference. If it should be desired to raise all of the sashes simultaneously, all of the switches 28, 29 and 30 are pressed upward. This action causes the rod 31 to pivot the lugs 32, thus urging them to the position shown in the upper position of Figure 6. The latches are thus independent of the lu s, and the spring 33 urges the latch toward the screw threaded shaft 6, whereby the thread segment 25 may engage therewith. The crank 17 is then applied to the squared shaft 16 and turned, thereby revolving the horizontal shaft 11 through gears 14 and 13, likewise imparting simultaneous rotationto the several vertical shafts 6. This movement causes the sleeves 20 and 22 to move toward one another to co-operatively move the arms 19, 21 and 23.

Prior to operating the sashes individually, it is necessar first to close them by reverse rotation of the crank 17, and assuming for example, it is desired to open only the top sashes; all of the switches, except 28, controlling the upper sash are pressed up, while 28 is pressed down. This action obviously holds the latches 24 out of engagement with the shafts 6 in the former case and effects engagement in the latter instance. The crank 17 is rotated as previously set forth.

It will be understood that the above de scribed action applies equally to all of the as many more may be used as deemed sashes individually-or collectively, and it is understood that the number of sashes is not restricted to six, the number shown, and prac-: tical for the operation described. j Manifestly, theconstruction shown is capable of considerable variation, and such.

variation as iswithin the. scope of the a pended claims, is considered within t e sashes when the shafts are operated, said spirit of the present invention.
